BOTTL E-STOPPER.

SPECIFICATION forming part of Letters Patent No. 708,749, dated September 9, 1902.

Application filed January 20, 1902. Serial No. 90,518. (No model.) i

To aZZ whom it mazf concern:

Be it known that I,MARGARET 0. WILSON, a citizen of the United States, residing in the city of Chicago, county of Cook, State of Illinois, have invented a new and useful Improvement in Bottle-Stoppers, of which the following is a specificatiom My invention relates to bottle-stoppers, and

. has for its object the prevention of the refilling of the bottle whereto it is applied.

1 attain my object by the mechanism illustrated in the accompanying drawings, in which-- f Figures 1 and 2 are side views of the device, showing the stopper in a closed and open position, respectively, The bottle is shown in central vertical section, and in order to illustrate the operation of the device in Fig. 1 the bottle is shown in an upright position and in Fig. 2 in an inverted position. Fig. 3 is a fragmentary view of the locking device looking in the direction of the arrow, Fig. 1. Y

Similar numerals refer to similar parts.

' 2 and terminates at its lower. extremity in the centrally-apertured depending sleeve 3. Said casing is held in place-in the lower portion of the neck 4 of the bottle by. means of the washer 5, which consists of rubber, cork, or other suitable material. The stem 6, formed at the upper extremity of the slotted headpiece 7, fits loosely within said sleeve 3 and has a head 8, formed at-its upper extremity, so as to bear upon the upper extremity of said sleeve 3, thereby holding said stem in position in said' sleeve, but permitting the free rotation of said stem. A shoulder 9 is formedon said headpiece at the lower extremity of said sleeve to limit the longitudinal movement of said headpiece in said sleeve. Said headpiece 7 terminates at its lowerextremity in the loops 10, which are annular except for the slots ll, whichextend toward said stem 6. The rotatable key 12,-which is mounted in said loops, is cylindric in-cross section, having a circular portion 13, fitting the inner diameter of said loops, and a tongue portion l-t, designed to enter into said slots 11. The parts are so constructed that when said key in said loops 10. Said concentric position i is illustrated in Fig. 1 0t thedrawings, while Fig. 2 shows the tongue 14; within said slots Thus the position of said key tongue 14 is not adjacent to said slots 11 said 11, and consequentlythe key in its position nearest to said stem 6. The weight 15is suspended from said key 12 bymeans of the wires 16 16, which are extended across said loops 10, so as to constitute keepers for retaining the key in position within the loops.

The valverod 17 is secured at one end to the valve 2', above mentioned, and at the opposite end terminates in a ring 18, which fits over the key 12, so as to be at all times concentric therewith, but loose enough to permit the free rotation of said key. It is evident, therefore, that the motion ofsaid key in the direction of the axis of the stem 6 is Said stem 6 iscen-' imparted to said ringlS; trally apertured to loosely receive said valverod 17 and permit the travel of the latter in the direction of the axis of said stem. The swivel 19 is placed in said rod 17 within the center casing 1 andis located between the 'valve 2 and'the upper extremity of the stem 6..

Said swivel is so constructed as to permit the independent rotation of the twodifierent sections of said valve 17 and also to permit the approach of said rod-sections toward each,

other telescopically. The parts are so proportioned that when the key 12 is concentric with the loops 10 the valve 2 is seated and the valve-rods 17 are in their extreme positions in the swivel'19.

The center casing 1 is provided at its lower portion with the apertures 2020, which form a passage for liquid. Above the center casing in the neck of the bottle are fixed the shelves or diaphragms 21, Whichextend part way across the neck of the bottle, so as to permit the passage of liquid, but prevent access to the valve 2.

A ring 22, carrying a weight 23, is loosely mounted upon the sleeve 3 and headpiece 7 in such a manner as to rotate freely thereon and also slide in the direction of the axis of said sleeve. Said ring and weight constitute a guard for preventing the opening of the valve 2 when the bottle is in an upright position, as will hereinaftermore fully appear.

The operation of the mechanism is as follows: When the bottle is held in an upright position, the weight 15 tends to drop to its lowest position, with the result that the key 12 assumes a position concentric with the loops 10, as shown in Fig. 1. The keyin this position causes the ring 18, acting through the medium of the valve-rod 17 and swivel 19, to draw the valve 2 down upon its seat in the center casing 1, thereby closing the bottle. When it is desired to remove the contents from the bottle, the bottle is inverted, which causes the weight 15 to approach the sleeve and swing the tongue 14 of the key 12 into the slots 11, with the result that said key and the ring 18 move toward said sleeve 3. This permits the valve 2 to drop from its seat, thereby permitting the escape of liquid from the bottle. Inasmuch as the headpiece 7 and valve-rod 17 are swiveled the weight 15 will be free to be acted upon by gravity when the bottle is in an approximately horizontal position, so that said weight is at all times operative.

It will be understood that if the bottle were shaken when in an upright position the weight might be caused to temporarily approach a position near the sleeve 3 and thereby permit the opening of the valve 2 for a short period of time in the attempted fraudulent refilling of the bottle. The function of the guard 22 and weight 23 is to prevent such approach of the weight 15 toward the sleeve 3. If the bottle were in an upright position, said guard would lie at the lowest extremity of its point of travelon the sleeve 3, notwithstanding the shaking of the bottle, and when said guard is in this last-named position said weight 23 assumes a location such as to interfere with the weight 15 and prevent a rotation of the key 12 sufficiently to permit the tongue 14 to enter the slots 11 in the loops 10. When, however, the bottle is held in an inverted position, said guard falls to a position adjacent to the body of the center casing 1, where it does not interfere with the swinging of the weight 15. One of the purposes, also, in providing the telescopic swivel 19 in the valve-rod 171s to add a further safeguard against fraudulent refilling by shaking the bottle, for it will be apparent that if the bottle be held in an upright position the weight of the valve 2 will keep said valve down upon its seat even though the tongue 14 be caused to enter the slots 11. In this latter instance the parts of the valve-rod 17 would merely telescope within the swivel 19, thereby virtually shortening the length of said valve-rod and rendering said rod inoperative to raise said valve from its seat.

What I claim as new, and desire to secure by Letters Patent, is-

1. In abottle-stopper, the combination of a center casing secured to the neck of the bottle, a valve seating on said casing, a slotted loop connected to said casing, a rotatable key mounted in said loop and havinga tongue for entering the slot in said loop, a valve-rod consisting of two parts, whereof one is connected to said key and the other is connected to said. valve; and a telescoping swivel connecting the parts of said rod.
